I'll write a manual on creating a compiled install file later when I have more free time. In the meantime, I uploaded the ready-made file with the Dutch MUI. This is for the citizens of the Netherlands.
The installation package for the English-speaking people will be ready later.Chuwi_Hi8_PRO_Win10_16299.15_x86_nl-NL.zipReadme.pdf(522.47 KB, Downloads: 36)

I want to make a single boot Windows tablet of my dual boot Windows/Android tablet and creating a one big C: drive.
You have attached a Read me PDF file, but which steps I have to do to make it a single boot Windows system?
Is it only following step "Creating a bootable media and flash Windows" or also "Preparing this install file for a SingleOS tablet and for removing Android in DualOS tablet"?

Hi again,
You can read the section of the Readme document Preparing this install file for a SingleOS tablet and for removing Android in DualOS tablet.
Considering that you will be the first user who uses this compiled setup file, I would like you to test it first as is. So, please flash Windows in DualOS mode, to keep the Android untouched. It will take you about 30 minutes of your time.
Check the operation of both systems after Windows flashing, please.
Then, edit the Main.cmd as described in the manual and repeat flashing Windows with Android removing.
Good Luck!

Hello didsbury,
Hello guys,
I'm still waiting for your driver packs. Please upload it to a cloud and share, then send the link to my E-mail.
I need all drivers of all versions of the tablet to make universal install file for Hi8 pro.
Keep in touch.

I create a bootable media and flash Windows just like you discribed it. It went very well and now I have Windows with just over 12 GB available C: disk space.
Now I want to make it a single boot Windows tablet. Have I just to do the same again, but then changing "set OS_Attributes=2" into 1 in the script folder of the flash drive?

Thank you for conducting the test.
As I wrote above and in Readme, you need to edit the Main.cmd file by changing "set OS_Attributes=2".
It should look like this:set OS_Attributes=1
Then flash Windows again to remove Android.

Guys, please do not send me links to Dropbox and other such things. I can not install any garbage apps. There are many other ways. I prefer to use a free Google Drive, for example.
Why 1 Gb? It must be about 350Mb!
